034Motorsport is proud to offer our Billet Aluminum Diverter Valve for various Audi, Porsche, and Volkswagen vehicles! This high-quality, performance engineered diverter valve is designed to replace the factory plastic diverter valve, which is a common source of boost leaks. Unlike the OEM valve, which uses a fragile rubber diaphragm that is prone to failure, the 034Motorsport Diverter Valve features a high-performance spring and piston design. This means that the valve lasts much longer, and is capable of handling increased boost pressure.
Designed to be an affordable, no compromise replacement for the factory diverter valve in 1.8T, 2.2T, 2.7T, and 4.2T applications, the 034Motorsport Bypass Valve features 1" inlets and outlets.
The 034Motorsport Bypass Valve is fully serviceable and rebuildable.
Billet Aluminum Construction
Available in Polished Aluminum or Black Anodized Finish
Proven High-Performance Spring & Piston Design for Performance & Durability
Installed a pair of these in my RS4 and and the quality and fitment is second to none. You can service them yourself, just as with far more expensive valves. I instantly noticed an improved boost hold over the worn out OEM ones. One thing less to worry about!
I have switched from a passat and other Audi models and love that you can service it yourself. Much better than oem and sounds like bov with correct set up.

Beautiful product. very cost effective compared to the other after market solutions. I like the fact that I can take it apart to clean it out however it might be nice to make the Diaphragm available for purchase separately should it ever need to be replaced. Also, I ordered the polished aluminum and received the anodized black model. That is the only reason I gave this product 4 stars and not 5. I am sure 034 would have done everything they could to fix this problem, but I decided I liked the black model and kept it.
